Fallows has an interesting column in the the NY Times about the power of that other low-cost P2P distribution network, the US Mail. He focuses mostly on the Netflix example (mentioning Long Tail implications) and then brings in others: "Consider Postal Service fulfillment of transactions made on the Internet. About two million prescriptions a day - roughly one-fifth of the total - are delivered by first-class mail. EBay's vendors list five million new items daily, and those that are sold ship mainly by mail. One Pitney Bowes study found that online retailers were increasingly using paper catalogs sent through the mail to steer people to their sites."

Lowering the economic costs of niches is key to the Long Tail, especially for small purchases such as a single track. I mentioned in the post on variable pricing that below $0.49/track the transaction costs of processing the payment can start to get in the way. So the news that PayPal is changing its policies to encourage smaller transaction is good to hear. From the report: "PayPal’s transaction fee is typically volume-based, and ranges from 1.9 to 2.9 percent in addition to a charge of $0.30 per transaction. In the case of [the new model for] micro payments, which PayPal describes as payments of less than $2, the fee is 5 percent plus $0.05 per transaction."
